Choose details you can track
For a person, use a clear face and enough surrounding head and shoulders to understand the pose. For a product, include the whole object and preserve a readable outline against the background. An asymmetric feature is useful because it helps you tell a true change of viewpoint from a mirrored image. Keep a real reference view for your own evaluation if you already have one.
Transparent, reflective and highly patterned objects can be especially difficult to judge. Reflections may be regenerated and small lettering may change. A busy arrangement introduces more relationships between objects than a single item does. Start with a source whose important features you can list and inspect. Do not use a successful portrait as evidence that every type of product will behave equally well.
